CHALK-HOLDER.

Specification of Letters Patent.

Patented Dee. 6, 1910.

Application filed May 2, 1910. Serial No. 558,929.

To all whom fit may concern:

Be it known that I, JOHN J. SAYLns, a citizen of the United States,residing in the city and county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Chalk-Holders; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

My invention relates to a chalk-holding device, adapted for use bycarpenters and p thers who are accustomed to use a chalk The object ofmy improved device is t0 facilitate the chalking of a line, and at thesame time economize the chalk, since with my improved holder it becomespracticable to use the chalk evenly, or approximately so until it ispractically consumed.

My improved device consists of a body memberl which is semispherical inshape and provided wit-h a bottom disk adapted to swing away from thebody member, whereby the latter is opened fo-r the reception of thechalk, after which the movable bottom is returned to its normal positionand maintains the chalk in place. This bottom is connected with the bodyof the device in such a manner that the body member' is sup` ported orraised slightly above the bottom i to allow the chalk line to enter, thebottom plate or disk being equipped with a lip projecting somewhatbeyond the semispherical body part, and thereby forming a stop o-r catchfor the line, whereby the latter is guided into the holder andunderneath the cake or block of chalk. The portion of the body memberremote from the movable disk, is provided with an opening' adapted toreceive the thumb of the user, whereby the chalk may be presseddownwardly upon the line during the operation of chalking the latter.

Having briefly outlined my improved construction, I will proceed todescribe the same in detail, reference being made to the accolnpanyingdrawing in which is illustrated an embodiment thereof.

In this drawing: Figure 1 is an underneath view of my improvedchalk-holder showing the line in place for chalking purposes. Fig. 2 isa top plan view of the same. Fig. 3 is a side elevation of the chalkholder, also showing the line in place. Fig. l is an underneath view ofthe bottom plate or disk swung to one side to permit the insertion ofthe chalk. Fig. 5 is a sectional view of the device showing the chalk inplace. Fig. G is a view similar to Fig. 3, but showing the device heldin the hand of the user, `as in the operation of chalking a line.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the body member of my improved chalk-holder,the same being illustrated as approximately semispherical in shape, asegment of the body member being removed, as shown at 6, to form anopening 7 for the introduction of the thumb of the user while clialkingthe line. lVhile this holder, as shown in the drawing, has the shape ofthe segment of a sphere, it is evident that this shape may be varied toaccommodate a block of chalk of any desired shape. These cakes orblocksof chalk are generally made semispherical or having the shape of asegment of a sphere, and it is for this reason that the body of myimproved holder has the shape mentioned. This body member is providedwith a perforated ear 8 which is pivotally connected by means of a rivet9 with aplate or disk l0 which forms the bottom of the body-member andserves to prevent the escape of the chalk 12 when the device is in use.The ear 8 of the body member projects somewhat below the plane of thelower edge of the said member, so that when the plate or disk l0 isconnected therewith by a rivet or other suitable fastening device 9, thesaid plate or disk will extend slightly below the lower edge of the bodymember, sullicient space heilig thereby provided to allow the cord 13 toenter. This disk or plate, forming the bottom cover or closure of thehollow body-member, when the device is in use, is rovided directlyopposite the rivet pivot with a lip 14;, which acts as a guide indirecting the line into the chalk-holder, whereby it is caused to passunder the block of chalk, which may be pressed down upon the bottomplate or closure 10 as indicated in Fig. 6.

From the foregoing description, the use of my improved device will bereadily understood. Preparatory to the use of the device for chalking aline, a piece of chalk l2 is placed in the boX, after which the bottomplate or closure 10 is swung into place or to its normal position.rI`hen by the aid of the guide lip 141:, the line 13 is caused to slipinto the device between the bottom l0 and the adjacent edge of thesemispherical body portion. Then by pressing down upon the chalk withthe thumb (see Fig. 6), after the line is in place underneath the chalk,the line may be quickly and easily challred, with practically no loss ofmaterial.

Having thus described my invention, what I claim is:

l. A device of the class described, comprising a hollow, semi-spherical,body member, having an opening in the top, an ear offset from the planeof its lower edge, and

a plate or cover pivotally connected with the I said ear to swing in aplane transversely thereof, substantially as described.

2. A chalk holder, comprising a hollow, semispherical, body member,having an opening in the top, and a plate offset from the base of thebody member, and pivotally connected therewith to swing in a planescribed.

In testimony whereoi'I affix my signature 1n presence of two witnesses.
